Solenoid Inspection

EGR Control Solenoid Valve Test:

1. Disconnect the yellow striped vacuum hose and the green striped vacuum hose from the solenoid valve.

2. Disconnect the electrical harness connector.

3. Connect a hand vacuum pump to the green striped hose nipple.

4. Connect jumper leads to the solenoid terminals.

EGR Control Solenoid Valve Voltage Test:

5. While applying vacuum to the solenoid, apply battery voltage directly to the solenoid terminals.
Vacuum should HOLD.

6. Discontinue voltage.
Vacuum should LEAK.

EGR Control Solenoid Valve Resistance Check:

7. Measure the resistance between the terminals of the solenoid valve.
